摘要

我们首先确定了在基于移动IP的系统中，将分布式系统的传统因果消息日志方法用作移动节点容错技术时出现的一些问题。然后，我们提出了一种新的具有独立检查点的因果消息记录协议，以有效地处理移动节点的移动性和断开性、电池寿命有限、存储容量小和无线链路带宽低等约束。此外，与以前的因果消息日志记录协议相比，该协议可以大大减少垃圾收集移动节点日志信息时所需的额外消息和强制检查点的数量。

Low-cost fault-tolerance for mobile nodes in mobile IP based systems

We first identify some problems occurring in the case where a traditional causal message logging approach for distributed systems is used as a fault-tolerance technique for mobile nodes in Mobile IP based systems. Then, we present a new causal message logging protocol with independent checkpointing for efficiently handling several constraints of mobile nodes such as: mobility and disconnection, limited life of battery power, small amount of storage and low bandwidth on wireless link. Moreover, the protocol can considerably reduce the number of additional messages and forced checkpoints needed when garbage collecting the log information of mobile nodes compared with previous causal message logging protocols.
